Convection Currents and the Mantle 1.2




Vocabulary:


Heat Transfer: The movement of energy from a warmer object to a cooler object.
Radiation: The transfer of energy through empty space.
Conduction: Heat transfer by direct contact of particles of matter.
Convection:Heat transfer by the movement of a heated fluid.
Density: A measure of how much mass there is in a volume of a substance.
Convection Current: The flow that transfers heat within a fluid

      • density
      • convection current
      • heating, cooling fluid changes density
    • Convection in Earth's Mantle
      • convection currents- rise through asthenosphere
